Money Flow Index (MFI)
A momentum indicator that uses a stock’s price and volume to predict the reliability of the current trend. Because the Money Flow Index adds trading volume to the Relative Strength Index (RSI), it’s sometimes referred to as volume-weighted RSI.

Rate of Change (ROC):
The speed at which a variable changes over a specific period of time. Rate of change is often used when speaking about momentum, and it can generally be expressed as a ratio between a change in one variable relative to a corresponding change in another. Graphically, the rate of change is represented by the slope of a line.

Slow Stochastics:
A technical momentum indicator that compares a security's closing price to its price range over a given time period. The oscillator's sensitivity to market movements can be reduced by adjusting the time period or by taking a moving average of the result. This indicator is calculated with the following formula:
%K = 100[(C - L14)/(H14 - L14)]
C = the most recent closing price
L14 = the low of the 14 previous trading sessions
H14 = the highest price traded during the same 14-day period.
%D = 3-period moving average of %K

Average True Range:
A measure of volatility introduced by Welles Wilder in his book: New Concepts in Technical Trading Systems.
The true range indicator is the greatest of the following:

current high less the current low.

the absolute value of the current high less the previous close.

the absolute value of the current low less the previous close.

The average true range is a moving average (generally 14-days) of the true ranges.

Moving Average Convergence Divergence (MACD):
A trend-following momentum indicator that shows the relationship between two moving averages of prices. The MACD is calculated by subtracting the 26-day exponential moving average (EMA) from the 12-day EMA. A nine-day EMA of the MACD, called the "signal line", is then plotted on top of the MACD, functioning as a trigger for buy and sell signals.

Relative Strength Index (RSI):
A technical momentum indicator that compares the magnitude of recent gains to recent losses in an attempt to determine overbought and oversold conditions of an asset. It is calculated using the following formula:
RSI = 100 - 100/(1 + RS*)
*Where RS = Average of x days' up closes / Average of x days' down closes.

Commodity Channel Index (CCI):
An oscillator used to help determine when an investment vehicle has been overbought and oversold. The Commodity Channel Index, first developed by Donald Lambert, quantifies the relationship between the asset's price, a moving average (MA) of the asset's price, and normal deviations (D) from that average.

Williams %R:
A momentum indicator measuring overbought and oversold levels, similar to a stochastic oscillator. It was developed by Larry Williams and compares a stock's close to the high-low range over a certain period of time, usually 14 days.
